Next followed something of more curious and even startling interest. A chemist at Budapest, where the first rumors of Syx’s reappearance had placed the mysterious doctor, announced that he could produce artemisium, and proved it, although he kept his process secret. Hardly had the sensation caused by this news partially subsided when a similar report arrived from Ekaterinburg; then another from Batang; after that a fourth from Nicolosi!

Nobody could fail to notice the coincidence; wherever the doctor—or was it his ghost?—appeared, there, shortly afterwards, somebody discovered the much-sought secret.

After this Syx’s apparitions rapidly increased in frequency, followed in each instance by the announcement of another productive artemisium mill. He appeared in Germany, Italy, France, England, and finally at many places in the United States.

“It is the old doctor’s revenge,” said Hall to me one day, trying to smile, although the matter was too serious to be taken humorously. “Yes, it is his revenge, and I must admit that it is complete. The price of artemisium has fallen one-half within six months. All the efforts we have made to hold back the flood have proved useless. The secret itself is becoming public property. We shall inevitably be overwhelmed with artemisium, just as we were with gold, and the last condition of the financial world will be worse than the first.”

My friend’s gloomy prognostications came near being fulfilled to the letter. Ten thousand artemisium mills shot their etheric rays upon the moon, and our unfortunate satellite’s metal ribs were stripped by atomic force. Some of the great white rays that had been one of the telescopic wonders of the lunar landscapes disappeared, and the face of the moon, which had remained unchanged before the eyes of the children of Adam from the beginning of their race, now looked as if the blast of a furnace had swept it. At night, on the moonward side, the earth was studded with brilliant spikes, all pointed at the heart of its child in the sky.

But the looting of the moon brought disaster to the robber planet. So mad were the efforts to get the precious metal that the surface of our globe was fairly showered with it, productive fields were, in some cases, almost smothered under a metallic coating, the air was filled with shining dust, until finally famine and pestilence joined hands with financial disaster to punish the grasping world.

Then, at last, the various governments took effective measures to protect themselves and their people. Another combined effort resulted in an international agreement whereby the production of the precious moon metal was once more rigidly controlled. But the existence of a monopoly, such as Dr. Syx had so long enjoyed, and in the enjoyment of which Andrew Hall had for a brief period succeeded him, was henceforth rendered impossible.

XIV. THE LAST OF DR. SYX

Many years after the events last recorded I sat, at the close of a brilliant autumn day, side by side with my old friend Andrew Hall, on a broad, vine-shaded piazza which faced the east, where the full moon was just rising above the rim of the Sierra, and replacing the rosy counter-glow of sunset with its silvery radiance. The sight was calculated to carry the minds of both back to the events of former years. But I noticed that Hall quickly changed the position of his chair, and sat down again with his back to the rising moon. He had managed to save some millions from the wreck of his vast fortune when artemisium started to go to the dogs, and I was now paying him one of my annual visits at his palatial home in California.

“Did I ever tell you of my last trip to the Teton?” he asked, as I continued to gaze contemplatively at the broad lunar disk which slowly detached itself from the horizon and began to swim in the clear evening sky.
